Bloomberg buys BusinessWeek - reports on Twitter

As of 6:58pm EST tonight, I saw the following on my Twitter feed from Steve Rubel:

RT @davidburn: RT @JohnAByrne - BW's Tom Lowry is reporting that Bloomberg has reached a deal to buy BusinessWeek. http://is.gd/4i7hl.

I was so intrigued that I found out this news via Twitter from the company's insiders before I'm hearing it from a vetted, editorial news outlet. Is this how you filter your news? Is this the future of breaking news?
